B. Helen should have added 17 to both sides of the equation.
When trying to solve an equation like that with a variable, you have to make sure both sides are even. Whatever you do to one side, you have to do to the other. So, if you add 17 to one side to cancel it out, you have to add 17 to the other side as well.

Which statement is true about f(x) = –6|x + 5| – 2?
Ad libitum [116K]
The graph of f(x) opens upward

For the values of x < -5 the function is a line with negative slope, for the values of x > - 5 the function is a line with positive slope.

The two lines intercept in the point (-5,-2). That is the vertex of the function; a minimum value. So, all the other points are above the line y = -2.

A teacher plans to buy air fresheners that cost $3.50 each. If the teacher can spend no more than $10 on the air fresheners and
iris [78.8K]

Answer:

Step-by-step explanation:

We need to create an equation to represent how many air fresheners the teacher can buy.

Teacher has $10 and a $3 discount coupon which would give her an extra $3 to spend. Each air freshener is $3.50.

x = number of air fresheners

($10 + $3) / $3.50 = x        can be written as $13/$3.50 = x

We add $10 and $3 because that gives us the total amount she has to spend.

We divide by $3.50 because that is the cost of each air freshener. The result is the number of air fresheners she can buy.

In this case.

$13/$3.50 = x

3.71 = x   BUT we can't buy part of an air freshener, so she can purchase 3 air fresheners.
